Changed ROM now "Process System" not responding.

I changed ROMS from Liberty to Apex. My battery completely died and now whenever I boot it I get the message "Process system is not responding", I can hit "Force Close" or "Wait" neither one does anything after I push it. I can boot up into the Bootloader D2.37 using UP+Power. Can I start fresh from here? ADB can't seem to find the device (using Fedora Linux, yes I changed the udev rules, but I don't know if they are correct because there's no Fedora instructions.) but it shows up when I do lsusb.
